You are going to have to give us a clue why you
should NOT use BYSCL. Is this a religious preference?

It is hard to imagine how you are going to improve
*visual* contrast without byte scaling something!

If you want to improve the contrast in your array
locally, you might try a program like XSTRETCH:
